Question

The ice cube kept at room temperature melts on its own. which law of thermodynamics is obeyed by the reaction?

Answer 1

Melting ice is a physical, reversible change.

This is due to the fact that only the state the ice is in changes when heat is applied; the chemical base is not changed.

Explanation:

The change in entropy of the system or the surroundings is the quantity of heat transferred divided by the temperature.

The second law of thermodynamics states that in a reversible process, the entropy of the universe is constant, whereas in an irreversible process, such as the transfer of heat from a hot object to a cold object, the entropy of the universe increases.
